Symptoms of myocardial infarction have some common manifestations

Too many people have lost their precious lives because of a sudden myocardial infarction. This is because people have ignored the danger signals from myocardial infarction and caused many accidents that could have been avoided.

So what are the symptoms of myocardial infarction?

How to prevent myocardial infarction?

Below we will explain one by one.

Symptoms of myocardial infarction are common symptoms 1. Pain pain is the most prominent symptom of myocardial infarction.

There are obviously no obvious incentives, and often in quiet, the pain site and nature are the same as angina pectoris, but the pain is heavier and lasts for a long time, for hours or even days, with nitroglycerin.

Common Symptoms 2: The main factors of shock shock are: due to severe damage of myocardial infarction, the left ventricular displacement is drastically reduced; secondly, chest pain leads to nerve reflex peripheral blood vessels dilatation; thus, due to vomiting, sweating, insufficient replacementThere are factors that cause insufficient blood volume.

Common symptoms 3: arrhythmia atrioventricular remodeling block, bundle branch block is too common, supraventricular arrhythmia often occurs.

Myocardial infarction in the anterior wall is prone to bundle branch block, and inferior myocardial infarction is prone to atrioventricular block, and supraventricular arrhythmia is more common in atrial infarction.

Common symptoms 4: Heart failure after heart failure is significantly weakened and uncoordinated, so acute left heart failure occurs in the first few days of onset, dyspnea, cough, irritability, and can not be supine.

Severe cases of acute pulmonary edema, may have purpura and a large number of pink foam-like sputum, late heart failure, right ventricular myocardial infarction at the beginning of right heart failure.

Common Symptoms 5: Systemic symptoms of systemic symptoms include fever, tachycardia, increased white blood cells and increased red blood cell metabolism.

This is mainly caused by tissue necrosis, usually 1-2 times after infarction, the body temperature is generally around 38 ° C, rarely more than 39 ° C, lasting about a week or so.
